If your GM Coil has two connectors, usually one gray and one black, this is a direct replacement performance coil. This style coil was used on pretty much anything that came out of GM until 1996 (except DIS systems). MSD's Blaster GM Coil features a red housing that surrounds a set of Blaster 2 influenced windings for improved output. The Coil mounts in the same location as the stock coil and plugs right in. If you plan to install an MSD Ignition with your Blaster GM Coil, use a PN 8876 Harness for a direct plug-in installation. 8226$43.99 Don't see what you want? .......... Need help?
